This paper presents the approach and results of porting the Long-Wave Rapid Radiative Transfer Model (RRTM) component of the Weather Research and Forecast (WRF) code to the GPU using CUDA Fortran. After a brief description of the RTTM code, considerations regarding porting the application to the GPU are discussed. Included in the porting discussion are how the data structures have been modified...

The Unified Model (UM) code supports simulation of weather, climate and earth system processes. It is primarily developed by the UK Met Office, but in recent years a wider community of users and developers have grown around the code. Here we present results from the optimisation work carried out by the UK National Centre for Atmospheric Science (NCAS) for a high resolution configuration (N512 ≈...

On the verge of the convergence between high performance computing (HPC) and Big Data processing, it has become increasingly prevalent to deploy large-scale data analytics workloads on high-end supercomputers. Such applications often come in the form of complex workflows with various different components, assimilating data from scientific simulations as well as from measurements streamed from s...

We provide the first two-party protocol allowing Alice and Bob to evaluate privately even against active adversaries any completely positive, tracepreserving map F ∈ L(Ain ⊗ Bin) → L(Aout ⊗ Bout), given as a quantum circuit, upon their joint quantum input state ρin ∈ D(Ain ⊗ Bin). Our protocol leaks no more to any active adversary than an ideal functionality for F provided Alice and Bob have th...

This paper presents the results of a study to quantify the performance of Weather Avoidance Fields in predicting the operational impact of convective weather on en route airspace. The Convective Weather Avoidance Model identifies regions of convective weather that pilots are likely to avoid based upon an examination of the planned and actual flight trajectories in regions of weather impact. Fro...

fifty street dust samples were collected from southern and eastern parts of tehran, the capitalof iran. samples were collected during summer under dry and stable weather conditions. total concentrationsof copper (cu), cadmium (cd), lead (pb), chromium (cr), nickel (ni), zinc (zn), iron (fe), manganese (mn)and lithium (li) were determined. ten samples were then selected for characterization, met...

We present WeatherTank, a tangible interface that looks like a vivarium or a diorama, and uses everyday weather metaphors to present information from a variety of domains, e.g., “a storm is brewing” for increasingly stormy weather, indicating upcoming hectic activities in the stock exchange market. WeatherTank represents such wellknown weather metaphors with real wind, clouds, waves, and rain, ...

InSAR signal delays due to the varying atmospheric refractivity are a potential data source to improve weather models [1]. Especially with the launch of the new Sentinel-1 satellites, which increases data coverage, latency and accessibility, it may become possible to operationalize the assimilation of differential integrated refractivity (DIR) values in numerical weather models. Although studie...
